David all XML props are accessed by prefacing with the @ symbol so
@prop1 in your example. Also values are treated as text in XML so you
will have to cast them as integer values to add them up or parse the
XML into custom class objects which is what I do.

Hey yall,
This seems like a pretty simple problem, which makes it all the more
frustrating that I can't get it to work right:
There is an XMLList of items, each item has three properties: prop1,
prop2, and prop3.
There are two TextAreas, t1 and t2.
t1 displays the XMLList.toString
t2 is blank
There are two buttons: Show and Clear.
When you click Show, the following should happen:
For each item in the XMLList, if prop3 is false and prop1 is "BB",
then add that item's prop2 to the text of t2.
My code is below.
It's only showing some of the results, not all expected. (It should
show L3a and L3y. It only shows L3y.)
What am I doing wrong?
